IMPROVEMENT IN DUMPlNG-CARS.

Specification forming part of Letters Patent No. 108,313, dated October18, 1870.

' To all whom it may concern:

Be it known that I, ANDREW J. BALLARD, of Cohoes, in the county ofAlbany and State of New York, have invented a new and useful Improvementin Beam-Doffers orDumping- Cars, of which the following is aspecification,

. reference being had to the accompanying drawing, in which- Figure 1represents a side elevation of my improved truck. Fig. 2 represents anend View of the same. Fig. 3 represents a similar view of the same withthe top lowered.

My invention is more especially adapted to the loading, transportation,and unloading of beams from warping'frames in factories for weaving andspinning textile fabrics; and my improvement consists in constructingthe truck with a top or platform so hinged that one of its sides or endsmay be raised or lowered by means of a lever, to facilitate the loadingand unloading of the truck.

In the accompanying drawing the truck is shown as composed of fourwheels, A, mounted on suitable axles, and connected by a proper frame,13. One pair of wheels is made to turn on a king-bolt in the usual way,to guide it properly.

A bed, table, or platform, 0, is mounted at one side or end upon hingedstandards 0. The other side or end rests upon a hinged frame, composedof a rook-shaft, I), mounted in'bearings in the bed, arms E, vibratingon the rockshaft, a connecting-bar, F, and friction-rollers G. Theselatter are flanged, and run on rails g on the truck.

A hand-lei'er, H, is pivoted on the rockshaft D, and raises or lowersone side of the bed by moving the rollers in or out, as shown bythedrawing.

A notch, g, in the rails g, serves to hold the rollers G in place, andthus keep the tablelocked in position when elevated, while a stop, 0,prevents its descending too far.

In operation the bed is lowered from the position shown in Fig. 2 tothat shown in Fig. 3 by lifting the hand-lever. The beam or otherarticle is then rolled on the table, the lever depressed, and the tableraised to a horizontal position. The load is discharged'by reversingthis operation.

Arms or levers might be hinged to the side of the bed to form aninclined plane, 'up which the article to be loaded might be rolled.These arms would, it short, be lifted out of the way by the rising ofthe table; or they might be folded over upon the load, to hold it inposition.

The fulcrum of the shaft F might be fixed either at the point occupiedby the axis of the roller in Figs. 2 or 3, and the friction-rollers G bemounted on the upper shaft, D, which latter would then vibrate aroundthe axis of the other shaft; but I prefer the mode shown.

I do not broadly claim a dumping or tilting bed mounted on a truck, asthat is common in railway-cars.

I claim as my invention- The combination of the bed, hinged to thecarrying-frame at one side, the rock-shaft, mounted in bearings on theother side of the bed, the frame vibrating around said shaft, thefriction-rollers, and the vibrating handlever, all these parts beingconstructed to operate in combination, substantially as herein beforeset forth.

In testimony whereof I have hereunto subscribed my name.

ANDREW J. BALLARD.
